In the U.K.'s House of Lords on Feb. 3, members of parliament debated expanding Great Britain's aid to the Democratic Republic of Congo, the site of several intersecting security and humanitarian crises. "Some 5 million people have died there since 1998," said Lord David Alton of Liverpool. "It is the most deadly conflict since World War II."
Alton based his figure for Congolese war deaths on a widely cited 2008 report from the International Rescue Committee, which claimed that 5.4 million Congolese had died of war-related causes between 1998 and 2007. The causes included starvation, disease and combat between government forces and rebel groups.
But one university group has challenged the IRC's report, and cast into doubt widely used methods for calculating war deaths in conflicts all over the world. The Human Security Report (.pdf), published in January by Simon Fraser University in Canada's British Columbia, rejects the IRC's Congo estimates, claiming they were based on "questionable methodological assumptions." The university report instead endorses a Belgian study that found just 200,000 Congolese war deaths between 1998 and 2004.
